2AlBr ---> 3Br + 2Al
what type of chemical reaction does this represent? decomposition? and....
Fe(NO3)3 + 3 NaOH ---> 3 NaNO3 +Fe(OH)3
the choices are...
synthesis... A+B ---> AB
decomp... AB --> A+B
single... A+BC ---> AC+B
double... AB +CD ---> AD + CB
thanks in advance

the first one is a redox reaction, Al3+ is reduced to metal Al, and Br- is oxydized to Bromine.
the correct equation is
2 AlBr3 --> 3Br2 + 2Al
This is a standard reaction made with electricity. It's called electrolysis.
The second reaction is just a salt exchange, so it can be called "double" from what you wrote, but i'm a chemist from 10 years and I never heard of this kind of terminology (single, double in particular)
